In the rapid growth of perovskite solar cells, there are still specific issues regarding the extensive absorption of incident photons. Double-layered methyl ammonium (MA)-free perovskite solar cells (PSC) have been proposed to sort out these issues. The material absorber in solar cells based on MA-free and cesium-based perovskite, i.e., Cs2BiAgI6, is a critical parameter because of its non-volatile nature as well as its band gap of 1.6 eV being helpful in a broader visible absorption spectrum than the conventional CH3NH3PbI3 material. Moreover, the quantum efficiency (QE) and power conversion efficiency (PCE) in a configuration with MXene + TiO2 as the electron transport layer (ETL) in the PSC can make improvements over a more extensive range. The results of the current modeling of numerical simulations are used to investigate the exclusive optoelectrical outputs of the PSC. Furthermore, we use a novel approach of an ETL of MXene + TiO2 in a PSC, which will lower the manufacturing cost and defectiveness. The present work compares different ETLs to attain the best PCE using Cs2BiAgI6 as a perovskite absorber layer (PAL). The results are exciting as the highest open circuit voltage (VOC) of 1.48 V, high short current density (JSC) of 22.8 mA cm-2, with a high fill factor (FF) of nearly 84.6% in the double-layered PSC offer a high power conversion efficiency (PCE) of more than 28%. The designed outputs will be efficient for the convenient fabrication of the PSC. [ABSTRACT FROM AUTHOR] |
